This is blowing my mind, I had no idea it was as good as it was. I always remembering it being slow, empty, and just not really usable. This is incredible work and I'm sorry that I held such a negative opinion of it for so long!

I held the same negative opinion, until about 2018. Then I thought "enough is enough" and started contributing in my area. This in the hope and expectation that other area's will have volunteers working who started out with the same emotion in a somewhat catalysing effect (is that a word?). Now I am quite proud of maintaining shops and bars in my city, at least I think I am the person who updates those the most :)

OSM needs some form of gamification adding to it. Google Maps app is great, lets you gain points by adding information & photos & reviews etc. They even send you a free bespoke pair of socks or a badge if you're active enough. So fun to add photos and then see how many views they get (I posted one of a chippy in Scotland (for Americans that's Fish & Chip 'Thick French Fries' shop) which got over 1.4 million views - m…

I maintain a website called MapRoulette which is not pure gamification but breaks down map contributions into small tasks. It has some elements of gamification (badges, leaderboard). For more task-based editing with gamification elements check out StreetComplete, an Android app.

if people don't know it -- MapRoulette is massively successful and a giant contribution to Openstreetmap

I've found that about 80% of the bullshit my search engine crawler finds is on Russian and Chinese IPs (especially the Alibaba Cloud). Not that there isn't legitimate content, but there seems to be very little effort put toward policing the bad as long as it primarily targets a western demographic. This is not by any means a new development.

Don't forget the Bayes theorem: lot of crap comes from ru/cn domains most ru/cn domains are crap.

The majority of English-language ru/cn domains being crap seems like a safe bet. I'm sure lots of legitimate businesses in those countries have such domains, but those websites aren't relevant to an English speaker not living in those countries.

OSM doesn't have a layer with just satelite images like Google maps has, does there exist any alternative here?

(Just to clear a possible misconception: OSM is a database, not a rendered map. Everyone is free to render their own maps based on OSM data.) When we map (e.g. when we click on the "Edit" button), we use satellite images from providers like Bing, Maxar, ESRI, who have authorised their imagery to be used as base layer. Many countries also authorize their national orthophotography to be used as base layer.

Openstreetmap.org does not have a satelite baselayer that I can use, so I don't get what you mean.

MapTiler released a ~500 GB high res dataset. Not sure on the licensing but I believe it can be used for free with attribution if self-hosting. https://data.maptiler.com/downloads/dataset/satellite-2021/#...

We have a subscription for MapTiler to do our in app maps; including very nice satellite imagery. This data set is obviously not the good stuff.

For reference, I've used ortho4xp to get some satellite imagery based x-plane scenery. I have several hundreds of GB of scenery like that for a few relatively small areas, like my home country the Netherlands, the area around Berlin, and a few more places. That scenery comes in at multiple GB (4-6GB) for just a single rectangle on the map (1 degree latitude by 1 longitude degree, depending on the zoom level. You typically use it at zoom level 17 but you can configure it to go for zoom level 19 near airports, which helps when coming in to land. This stuff is huge. At zoom level 19, you can see quite a bit of detail. It looks great from a few hundred feet up in the simulator.

What map tiler offers us looks like it is similar quality to that. I assume they are licensing some satellite data for this. Zoom level 19 resolution for the entire world is likely to be in the peta byte range. 500GB is probably zoom level 15 or 16ish. Still usable but not great if you want to zoom in and see details.

Edit. Another point is that zl 19 and better does not come from satellites but from air planes and isn't available everywhere (only in populated areas typically).

What they mean is that OSM is not a commercial product that licenses satellite or aerial imagery, so the website does not include this (it's really just a showcase of various info that's in the database, not meant to be fit for any particular purpose, although it's surprisingly good for general use).

However, some image sources are available under free licenses, or in Bing's case, a special license for drawing roads in OSM. Many of those can be found if you go into the edit mode, because the default web editor (iD) has those in the background layers menu.

I also used to have a lot of fun with the KeepRight tool. Something oddly satisfying about taking a small geographic area and completely removing all flagged "problems". Feels like taking an ugly .C file and fixing all the warnings and lint errors. Only problem with KeepRight is I found it had a lot of false positives.

how do i turn on english names for places that are labeled in local language?

It is not possible with raster tiles, but the OSM database might still have the name in English. (You can have a look into vector tiles like from MapTiler or their open source project openmaptiles.org) I just found this example (has nothing to do with openmaptiles as far I can see): https://js.protomaps.com/examples/multi_language.html

It actually is possible with raster tiles as well - see e.g. the local chapter work in France ( https://www.openstreetmap.fr ) or Germany ( https://www.openstreetmap.de ) or the osMap project with 10 different language versions ( https://wiki.openstreetmap.org/wiki/osMap ). All those are produced with raster tiles.

But you are right as this approach does not scale well in regard to using it for all languages out there. So a vector tile stack is a better approach for just switching languages.

I prefer OSM to Google Maps when looking at maps. You get better maps with more detail. But, I have to back to GM to find anything with an address. The business database on OSM is poor, and I don't think the system for estimating the location of an address on a street has been particularly good either.

They were terrible years ago on GM, so this is part of the evolution. But I can see how OSM will end up better than GM, like Wikipedia over Encyclopedia Brittanica, but it needs a bit more to get there.

Btw: the online process to make changes on OSM is wonderful and encouraging.
